    I. EXECUTIVE SUMMARY

    In September 2018, representatives of the New York State Department of Health met with the Village of Watkins Glen to conduct a sanitary survey of the public water system. This survey was performed in response to previous surveys and events related to the boil water order issued in August 2018. In response to the recommended improvements outlined by the DOH, the following engineering study provides a comprehensive analysis of the existing Village of Watkins Glen water system. These improvements include water supply, treatment, storage, and distribution system to address water age, infrastructure condition, and water quality. A hydraulic model was used to evaluate system performance and identify problem areas in the network. After a full economic analysis considering the capital costs, the recommended improvements were separated into individual subprojects. The following table lists each subproject with an associated cost.

    Project Description Est. Cost

    A Raw Water Intake & Pump Station $4,555,000

    B Water Treatment Plant $4,548,000

    C Steuben Street Tank $277,000

    D Steuben Street Pump Station $236,000

    E Distribution Network $5,972,000

    Total $15,600,000

    The Village, and users from the Towns of Dix and Reading comprise about 1,782 EDUs. According to the 2017 ACS survey, the Village MHI is $45,938. Based on the outstanding DOH violations and existing state of equipment, storage, and distribution, it is likely the Village would qualify for 0% Hardship financing through grant opportunities with EFC. Based on discussions with the Village leaders and financial advisors, the subprojects will be prioritized and addressed based on community need and associated financing as to limit a drastic increase in user cost. It is evident that the Village significantly benefit from a low interest loan and/or some grant funds to help offset these costs.

    It is recommended that this Preliminary Engineering Report be used to pursue funding assistance from multiple agencies, including the Environmental Facilities Corporation (EFC) through the Drinking Water State Revolving Fund (DWSRF) and Water Infrastructure Improvement Act (WIIA), USDA Rural Development (RD), and the New York State Office for Community Renewal Community Development Block Grant (CDBG) program.

    II. BACKGROUND

    The Village of Watkins Glen (“Village”) water district encompasses approximately 2.2 square miles and is situated in the central portion of Schuyler County at the south end of Seneca Lake. The Village is considering improvements to its water supply, treatment, and storage, and distribution system to address the age, condition, and water quality issues identified by the New York State Department of Health (DOH) public water system sanitary survey on November 30, 2018. The Preliminary Engineering Report (PER) includes documenting the existing Village water district system, identifying needed improvements, evaluating alternatives, preparing capital cost estimates, and presenting funding scenarios and estimated annual user costs. The PER planning effort will support future Village funding requests. The Village will likely seek funding from multiple agencies, inc
